'An object of the invention 1s to providea jointer whose parts Amay beseparated where- A by the member that isla plied directly to y anotherof difthe work may be replaced ferent form.

Another .object 'is the provision of a fjointer whose parts are adaptedto be loosened whereby the member that is applied directly to the workmay be changed in position to provide a new working surface. l ,i 6 vStill another object is to furnish a jointer for mason7s use that willprovide for interlchangin the actual -working member, or admit 0% itschange in position for presenting'a diil'erent working surfacethereonand yetso constructed that the, various parts will bethoroughlyrigid relatively.

To the end that the invention may be fully understood the accompanyingdrawing is provided wherein: l

Figure 1 is a side elevation of one -orm of v 25, the jointer of' myinvention'.

Figure 2 is a side elevation of aother form of the invention. A y

Figure 3 is a transverse section ofthe tool 'produced on line in bothFigures 1 wand 2.4 1

Figure 4 is an end elevation of theform of tool shown in Figure 1. f

Figures 5 and 6 are end elevations of t wo forms of av working memberusable with either type of device shown, and

Figure 7 shows in perspective a partvofv a holding portion of myimproved jointer.

In Figurevl the numeral 1 designates that portion or member of the toolthat is vdi,- rectly applied to the work. As shown in said ligure, andin Figure 5 which. shows the full size, the member is of square form, asis also true of the form ofto'ol shown in Figure '2, while in Figure '6it is shown of round form, or it may be any other form desired. v

A handle structure is shown in'said Figure 1 which in ther presentinstance comprises three parts, a grasping piece 2, and two" holdingportions 3, 4, theselatter portions being secured each at one of itsends to theL grasp' g piece 2 -b ,a screw 5 passing through al t ree holing them in rigid relation. l

The holding portions 3 and 4 lextend away :from the ends of the handle-2 andY at their or holding the same in place in the handle contrari.

free ends engage 'the ends of the member 1, said yholding portions beingsuitably formed to space said handle a desired distance from saidmember. ,The end of the portion 3 has a terminal end 6 to overlie theend of the member 1 and includes a iin 7, for example, on itsinner'surface adapted to lie in either of two grooves 8 ofy said member,said fin 'having an extension 6 to enter a central cavity 7 2. in theend of the member, Figiires' 5 and 6, by 'which the member is maintainein a iixed position relative to the handle.

The end of the portion 4 remote from the handle 2 has a terminal end9.similar to the "lo end 6 and includes a boss 10 substantially fparalleling the axis of the handle 2and lies in a socket 11 in saidmember 1. Both por-- tions 3 and 4..may be provided with lugs 12 tooverlie the-member 1 constituting a s'ad- 75 dle to receive thesaid\member into it as in Eigure 3. v Asstated' earlier herein my objectis to substitute one` form of the member 1 foranother as wellv as toenable the workman to present dierent working surfaces of a member tothe 'work` By loosening `the screwthe portions Sfand 4 may be separatedsufliciently 'to permit the fin 7 to draw out of the groove 8 inA whichit lies thus per- 85 mitting the member 1 to be removed and re- Y placedby another or to be rotated to any desired position whereupon the-screwupon bein tightened secured the parts relatively ri .It is clear in thisconnection that one soV \ o the portions 3, 4 may, if desired; be a rpart ofthe handle 2 so that by a suiiicient -loosening of the said screwthe other will have enough end movement to accomplish the end stated.

'.lhe form in Figure 2 is ada ted for use in working in narrow or con edspaces. It includes the member 1f of any of the forms mentioned and thehandle 2 has'attached thereto or formed therewith a hold- 100 vingportion 3 having saddle portions 12',./

if desired, and' the terminal end 62 including the fin 7 to lie in thegroove in the end of the member 1 as in the first instance, a" screw'8extending through the end 62 into' 105 the member' serving to completethe assembl v 1t' is to be understoodA that ,it is not my purpose toconfine myself to the exact modev of securing the members 1, 1 fromrotating structure since other methods are open lfor use, I havingdescribed and shown but one eiicient form for so doing.

I claim: j..

1. In a masons jointer, a handle, a member for application to the work,a portion extending from each end of said handle, each engaging anend/of the member positively supporting the same therebetween, one/ ofthe portions and the member having a portion complementary to oneanother adapted to engage for preventing the member rotating, a'nd meansto secure the handle and said portions relatively rigid and for clampingthe member between said portions.

2. A 'masons jointer including a handle, a holding portion extendingfromend thereof rigid therewith, and a part of which portion is disposedsubstantially parallel to the handles length including a saddle, a workengaging member adapted to engage the saddle, the said holding portionarranged to engage upon one end of the member, and means to secure themember and portion relatively.

3. A masons jointer including a handle, a holding portion'extending.from one end thereof rigid therewith, a part of which p0rtion isdisposed substantially parallel to the,

handles 4length including a saddleA in oneside thereof, a work engagingmember ada ted to be lodged in the saddle, said holding portion arrangedto engage upon an end o the member and having a iin extending from itssurface, said member having a groove in its end toreceive said fin, andmeans to secure the member and portion relatively.

4. A masons jointer Finclliding a handle, a holding portion extendingfrom .each end of the handle, a part of one of which is disposedsubstantially parallel to the handles length and having a saddle, a workengaging member adapted to be lodged in the saddle, each of said holdingportions arranged to engage an end of the handle,

stantially parallels the handles length and including a saddle, and eachalso including a terminal and disposed substantially at right angles tothe said handles length, a

tuv

work Aengaging member interposed between theqterminals and held therebyand having a groove in one end, and also adapted to be lodged in thesaddles of the said holding portions, a iin on one of the terminals toengage in the said groove in theend of the member, and means to securethe handle, the portions and the member relatively.

6. A masons jointer including a handle, a holding portion abutting uponone end of the same and ailixed thereto, a work engaging member havingrgroove across an end thereof, said holding portion havinga terminal endto receive the end of the member against it and including at that end afin to'engage in said groove, and means to HENRY F.
